FIGS. 4, 5, and 6 are diagrams for generating hand signal information of a personal mobility according to an embodiment of the present disclosure.

The personal mobility 1 may generate first hand signal information by recognizing a surrounding situation.

The first hand signal information may include at least one of size information of a hand signal, left or right position information of a hand signal, transfer direction information of a hand signal, and transfer range information of a hand signal.

Hereinafter, a method of generating first hand signal information according to a distribution of a plurality of personal mobilities in located within a predetermined range will be described.

Here, the distribution of the plurality of personal mobilities in may mean the number of the plurality of personal mobilities 111 located within the predetermined range, and detailed positions of the plurality of personal mobilities 111 located within the predetermined range.

In more detail, the detailed position of personal mobilities within the predetermined range may be a distance between the plurality of personal mobilities 111 and the personal mobility 1.

The predetermined range may mean a range within a certain distance in all directions of the front, rear, left, and right centering on the personal mobility 1, and the direction and distance may be set according to the user's selection.

For example, as shown in FIG. 4, the personal mobility 1 may recognize five personal mobilities of the plurality of personal mobilities in around the personal mobility 1.

If it is recognized that the number of a plurality of personal mobilities in located within a predetermined range is five, detailed positions of the plurality of personal mobilities 111 may be determined. Each distance between the personal mobility 1 and the determined plurality of personal mobilities 111 may be detected.

If it is determined that the distance is narrower than a certain distance, the size information of the first hand signal may be determined as a small hand signal. For example, as shown in FIG. 6, the small hand signal may be the transmission of the hand signal using the user's hand.

When it is determined that the detailed positions of the determined plurality of personal mobilities 11 are clustered in d zone based on the personal mobility 1, the personal mobility 1 may determine the position of the hand signal to the right. For example, when the hand signal position is to the right, the hand signal may be transmitted using the user's right wrist or right arm, as shown in FIG. 6.

The personal mobility 1 selects any one of a plurality of personal mobilities 111 for transmitting the first hand signal and may determine transfer range information of the first hand signal based on the detailed position of the selected personal mobility 11. In more detail, as shown in FIG. 5, the hand signal transfer range of the first hand signal information may be a personal mobility within a predetermined distance based on the personal mobility 1.

A hand shape corresponding to personal mobility within the predetermined distance may be set. For example, in order to transmit a hand signal to a personal mobility within a 7 m distance based on the personal mobility 1, the set hand shape may be the use of two fingers, but is not limited thereto.

For example, in order to transmit a hand signal to a personal mobility or pedestrian in front of the personal mobility 1, the set hand shape may be such that the palm is visible, but is not limited thereto.

For example, as shown in FIG. 4, the personal mobility 1 may recognize three personal mobilities of the plurality of personal mobilities 111 around the personal mobility 1.

If it is recognized that the number of a plurality of personal mobilities in located within a predetermined range is three, detailed positions of the plurality of personal mobilities in may be determined. Each distance between the personal mobility 1 and the determined plurality of personal mobilities 111 may be detected.

If it is determined that the distance is wider than a certain distance, the size information of the first hand signal may be determined as a large hand signal. For example, as shown in FIG. 6, the large hand signal may be the transmission of the hand signal using the user's arm.

When it is determined that the detailed positions of the determined plurality of personal mobilities in are clustered in b zone based on the personal mobility 1, the personal mobility 1 may determine the transfer direction of the first hand signal as a rear b zone.

For example, as shown in FIG. 4, the personal mobility 1 may recognize a plurality of personal mobilities in centered on the personal mobility 1.

If it is recognized that the number of personal mobilities in located within a predetermined range is one, a detailed position of the personal mobility 11 may be determined. The distance between the personal mobility 1 and the determined personal mobility 11 may be detected.

If it is determined that the distance is wider than a certain distance, the size information of the first hand signal may be determined as a large hand signal. For example, as shown in FIG. 6, the large hand signal may be the transmission of the hand signal using the user's arm.

When it is determined that the detailed positions of the determined plurality of personal mobilities 11 are clustered in d zone based on the personal mobility 1, the personal mobility 1 may determine the transfer direction of the first hand signal as a forward d zone.

Hereinafter, a method of generating first hand signal information according to a distribution of a plurality of pedestrians located within a predetermined range will be described.

Here, the distribution of the plurality of pedestrians may mean the number of the plurality of pedestrians located within the predetermined range, and detailed positions of the plurality of pedestrians located within the predetermined range.

In more detail, the detailed position of the plurality of pedestrians within the predetermined range may be a distance between the plurality of pedestrians and the personal mobility 1.

The predetermined range may mean a range within a certain distance in all directions of the front, rear, left, and right centering on the personal mobility 1, and the direction and distance may be set according to the user's selection.

For example, as shown in FIG. 4, the personal mobility 1 may recognize seven pedestrians around the personal mobility 1.

If it is recognized that the number of a plurality of pedestrians located within a predetermined range is seven, detailed positions of the plurality of pedestrians may be determined. Each distance between the personal mobility 1 and the determined plurality of pedestrians may be detected.

If it is determined that the distance is wider than a certain distance, the size information of the first hand signal may be determined as a large hand signal. For example, as shown in FIG. 6, the large hand signal may be the transmission of the hand signal using the user's arm.

When it is determined that the detailed positions of the determined plurality of pedestrians are clustered in c zone based on the personal mobility 1, the personal mobility 1 may determine the transfer direction of the first hand signal as a forward c zone.

For example, as shown in FIG. 4, the personal mobility 1 may recognize three pedestrians around the personal mobility 1.

If it is recognized that the number of a plurality of pedestrians located within a predetermined range is three, detailed positions of the plurality of pedestrians may be determined. Each distance between the personal mobility 1 and the determined plurality of pedestrians may be detected.

If it is determined that the distance is larger than a certain distance, the size information of the first hand signal may be determined as a large hand signal. For example, as shown in FIG. 6, the large hand signal may be the transmission of the hand signal using the user's arm.

When it is determined that the detailed positions of the determined plurality of pedestrians are clustered in d zone based on the personal mobility 1, the personal mobility 1 may determine the position of the hand signal to the right. For example, when the hand signal position is to the right, the hand signal may be transmitted using the user's right wrist or right arm, as shown in FIG. 6.

For example, as shown in FIG. 4, the personal mobility 1 may recognize one pedestrian around the personal mobility 1.

If it is recognized that the number of pedestrians located within a predetermined range is one, a detailed position of the pedestrian may be determined. A distance between the personal mobility 1 and the determined pedestrian may be detected.

If it is determined that the distance is wider than a certain distance, the size information of the first hand signal may be determined as a large hand signal. For example, as shown in FIG. 6, the large hand signal may be the transmission of the hand signal using the user's arm.

Based on the personal mobility 1, when it is determined that the detailed positions of the determined plurality of pedestrians are located between the d zone and the c zone, the personal mobility 1 may determine the transfer direction of the first hand signal as a forward d zone and a right c zone.

FIGS. 7A and 7B are flowcharts of a control method of a personal mobility according to an embodiment of the present disclosure.

The method starts in a state where the personal mobility 1 is driving (710). This state can be determined by the personal mobility 1.

When the personal mobility 1 is driving, the personal mobility 1 may determine whether the user's gesture has occurred (711).

In more detail, the user's gesture may be a user's gesture detected by a wearable electronic device 2 connected to the personal mobility 1 through wireless communication. When the user's gesture is detected by the wearable electronic device 2, the wearable electronic device 2 may transmit information corresponding to the gesture to the personal mobility 1. The personal mobility 1 may determine whether the user's gesture has occurred by receiving information corresponding to the gesture.

If it is determined that the user's gesture has occurred (yes at 711), the personal mobility 1 may determine whether the gesture is a meaningful hand signal (712).

In more detail, in determining whether the gesture is a meaningful hand signal, the personal mobility 1 may determine whether the gesture matches a predetermined gesture, and when the gesture matches, it may be determined as a meaningful gesture.

If it is determined that the user's gesture is meaningful (yes at 712), the personal mobility 1 may recognize a surrounding situation of the personal mobility 1 (713).

The recognizing the surrounding situation may be to recognize at least one of the number of personal mobilities located within a predetermined range of the personal mobility 1, the detailed position of the personal mobilities located within the predetermined range, the number of pedestrians located within the predetermined range, and the detailed positions of the pedestrians located within the predetermined range.

In the predetermined range, a direction and a distance may be set according to a user's selection of the personal mobility 1.

Recognizing the surrounding situation may be recognized based on image information obtained through a camera. In addition, it may be recognized based on location information of personal mobilities located within a predetermined range and location information of pedestrians located within a predetermined range obtained through an Intelligent Transportation System (ITS).

A device of the ITS may be mounted on a personal mobility located within a predetermined range, detect a position value of the personal mobility located within the predetermined range, and transmit the detected position value to the personal mobility 1.

In addition, the device of the ITS may be mounted on a wearable electronic device of a pedestrian located within a predetermined range, detect a position value of the pedestrian located within the predetermined range, and transmit the detected position value of the pedestrian to the personal mobility 1.

The personal mobility 1 may determine whether there is an object, e.g., the personal mobility, pedestrian, or vehicle, to which at least one hand signal is to be transmitted based on the surrounding situation (714).

If there is no object to which the hand signal is to be transmitted among the personal mobility, the pedestrian, and the vehicle (no at 714), the personal mobility 1 may repeatedly recognize the surrounding situation of the personal mobility 1 (715).

If it is determined that there is an object to which the hand signal is to be transmitted (yes at 714), the personal mobility 1 can check whether the position or direction of the object to which the hand signal is to be transmitted can be determined (720).

If the location or direction of the object to which the hand signal is to be transmitted cannot be determined (no at 720), it is determined that the location of the object to which the hand signal is to be transmitted is not correct, so that the surrounding situation of the personal mobility 1 can be repeatedly recognized (715).

If the location or direction of the object to which the hand signal is to be transmitted can be determined (yes at 720), the personal mobility 1 may determine a detailed position of the object to which the hand signal is to be transmitted.

The personal mobility 1 may check whether the object to which the hand signal is to be transmitted is located on the right or on the left (721).

The personal mobility 1 may generate left or right position information of the hand signal based on the position of the object to which the hand signal is to be transmitted. For example, when the location information of the hand signal is left, the user may generate information for suggesting use of the ‘left wrist or left arm’.

The personal mobility 1 may check whether the object to which the hand signal is to be transmitted is located in the front or the rear (722).

The personal mobility 1 may generate transfer direction information of a hand signal based on a location of an object to which the hand signal is to be transmitted.

The personal mobility 1 may determine whether a distance between an object to which the hand signal is to be transmitted and the personal mobility 1 is close (723).

If the distance between the object to which the hand signal is to be transmitted and the personal mobility 1 is not close (no to 723), the personal mobility 1 may generate first hand signal information including size information of a hand signal for suggesting use of a “large hand signal” to a user (724).

If the distance between the object to which the hand signal is to be transmitted and the personal mobility 1 is close (yes to 723), the personal mobility 1 may generate first hand signal information including size information of a hand signal for suggesting use of a “small hand signal” to a user (725).

For example, a small hand signal may transmit a hand signal using the user's wrist, and a large hand signal may transmit a hand signal using the user's arm.

The personal mobility 1 may generate the first hand signal information by including at least one of size information of the hand signal, left or right position information of the hand signal, transfer direction information of the hand signal, and transfer range information of the hand signal based on the location of the object to which the hand signal is to be transmitted.

A user who has boarded the personal mobility 1 may perform a first hand signal corresponding to the first hand signal information.

The personal mobility 1 may determine whether there are more objects to which the hand signal is to be transmitted around the personal mobility 1 (730).

If there is another object to which the hand signal is to be transmitted around the personal mobility 1 (yes to 730), the personal mobility 1 can return to step 713 to continuously recognize the surrounding situation of the personal mobility 1. If there is not another object to which the hand signal is to be transmitted around the personal mobility (no to 730), the personal mobility 1 can go END.

FIG. 8 is a flowchart of a control method of a personal mobility according to another embodiment of the present disclosure.

The method starts in a state where the personal mobility 1 is driving (810). This state can be determined by the personal mobility 1.

The personal mobility 1 may determine a user who has boarded the personal mobility 1 has performed a hand signal corresponding to the first hand signal information (820).

The personal mobility 1 may recognize a change in a surrounding situation within a predetermined range based on the personal mobility 1 (830). The personal mobility 1 may detect a speed value of whether a speed of a personal mobility located within the predetermined range has changed. In addition, the personal mobility 1 may detect a GPS value of whether a GPS of the personal mobility located within the predetermined range has changed.

If there is a change in the detected speed value and the GPS value, the personal mobility 1 may determine that the surrounding situation of the personal mobility 1 has changed (yes at 830).

When the surrounding situation of the personal mobility 1 is changed (yes at 830), the personal mobility 1 can check whether the surrounding environment has changed to correspond to the first hand signal (840).

If the surrounding situation of the personal mobility 1 is not changed (no at 830) or if the surrounding environment has not changed to correspond to the first hand signal (no at 840), the personal mobility 1 may generate second hand signal information for performing the first hand signal again (850).

The second hand signal may include the first hand signal information, and the second hand signal information may include feedback information for proposing to perform the first hand signal again.

A user who has boarded the personal mobility 1 may perform a second hand signal corresponding to the second hand signal information (860).

Meanwhile, the disclosed embodiments may be implemented in the form of a recording medium storing instructions that are executable by a computer. The instructions may be stored in the form of a program code, and when executed by a processor, the instructions may generate a program module to perform operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.

The computer-readable recording medium may include all kinds of recording media storing commands that can be interpreted by a computer. For example, the computer-readable recording medium may be ROM, RAM, a magnetic tape, a magnetic disc, flash memory, an optical data storage device, etc.
